Debian Security Advisory DSA 798-1 security@debian.org

Package : webcalendar
Vulnerability : remote code execution
Problem-Type : input validation
Debian-specific: no
CVE ID : CAN-2005-2717

A trivially-exploitable bug was discovered in webcalendar that
allows an attacker to execute arbitrary code with the privileges of
the HTTP daemon on a system running a vulnerable version.

The old stable distribution (woody) does not contain the webcalendar
package.

For the stable distribution (sarge) this problem has been fixed in
version 0.9.45-4sarge2.

For the unstable distribution (sid) this problem will be fixed
shortly.

We recommend that you upgrade your webcalendar package immediately.
